A 6-velocity gearbox also comes common. And when that’s not ample, an update was unveiled in December ’01 bringing 384Nm, another update arrived in late ’02 bringing 394Nm and yet another update in late ’04 brought a massive 412Nm. A slightly bigger intercooler, a twin-scroll turbo, aluminium pistons and also other inner mods are included in these running changes.

Stage two shut deck, based on the North American 1991-ninety four Legacy Turbo EJ22T engine employs exactly the same casting marks but by using a up to date thrust bearing to placement #five rather than #three. It Employs similar cylinder heads and IHI RHF 5HB turbocharger[11] to be a EJ20K STi but with a novel shut deck crank circumstance. The pistons and connecting rods are forged. Although getting shut deck, the block isn't going to element oil squirters for piston cooling, against the EJ20G shut deck block as well as the USDM-only Legacy EJ22T closed deck block.
